Posso vibecodare Lemon Squeezy?

Build a closest honest personal substitute for Lemon Squeezy in an empty repository.
Use Next.js 15, TypeScript, PostgreSQL, Drizzle ORM, Stripe Checkout, and S3-compatible storage; do not offer alternative stacks.
The core loop is: sell a small catalog of digital products through Stripe, deliver purchased files or lessons, and manage customers from a user-owned storefront, leaving tax remittance explicitly to the creator.
Make the first run work locally with one documented command.
Store all user data locally by default and make export straightforward.
Put secrets in .env, ship .env.example, and never commit credentials.
Implement products, variants, prices, files or lessons, coupons, customers, orders, and entitlements.
Use Stripe-hosted Checkout and verify every webhook signature and idempotency key.
Grant access only after confirmed payment and revoke it on refund or chargeback.
Create a customer library with signed short-lived download or lesson URLs.
Add order search, resend receipt, refund handoff, export, and an immutable event log.
Document taxes as the creator's responsibility and do not calculate unsupported jurisdictions.
Include clear empty, loading, success, and recoverable error states.
Add input validation, safe filenames, and graceful handling of unavailable APIs.
Write focused tests for the core transformation and one end-to-end happy path.
Create a README with setup, architecture, permissions, data location, and backup steps.
Do not add accounts, billing, telemetry, analytics, or a hosted control plane.
Do not claim to reproduce proprietary data, network liquidity, regulated access, or frontier infrastructure.
Deliberately leave out merchant-of-record tax remittance.
Deliberately leave out a buyer marketplace or affiliate network.
Deliberately leave out advanced communities, certificates, mobile apps, and enterprise learning features.
Finish by running the tests and listing the exact commands used.
